IMPROVEMENT IN MACHINES FOR CUTTING HEADS FOR BARRELS.

Specification forming part of Letters Patent No. 1 59,114, dated January26, 1875; application filed November 18, 1574 To all whom it mayconcern:

Be it known that I, OTTO. Os'lEN. of North Bend, Coos county, State ofOregon, have ther invention or experiment.

My invention relates to an improved machine for cutting outbarrel-heads.

In order to describe my invention so that others will be able tounderstand its construction and operation, reference is had to theaccompanying drawing forming a part of this specification, in whichFigure 1 is a perspective view of my invention. Fig. 2 is a plan view.

A is a horizontal frame, which is mounted upon legs B. O is a horizontalshaft, which is supported in boxes on the cross-timbers at one end, andmidway between the side timbers of the frame A. On the end of thisshaft, at the middle of the frame, I secure the headcutting tool. Thistool consists of a conical metal head, d, which has its apex or centersecured to the end of the shaft 0, so that its flaring or wide end willbe outward. This conical head I prefer to construct with a hollow orconcave interior. At two or more points in this head I make radial slots0, and upon the head over each slot I secure a cutter or bit, f, bymeans of bolts, which pass through the bits and slots, and are firmlyheld by nuts 2'. This bit is made long enough to project beyond the edgeof the conical head, and the projecting portion is sharpened preferablyat an angle. The bit can be set out or in, as desired, by loosening thenut t and shifting the position of the bolt in the slot e. G is asliding head, which is fed forward or back upon the side rails of theframe A by means of a screw, 71,, and crank I. The portion of thissliding head which is opposite the flaring or open end of the conicalhead is made square, so that a board can be placed against it and thesliding head moved up against the rotating cutters, and a circularbarrel-head or portion of a barrel-head cut out from the board. K is acurved clamping-bar, which is operated by a lever, L, from the end ofthemachine.

When the lever L is moved in one direction, the clamp-bar Kis moved outfrom the face of the sliding head, so that the board to be out can beplaced between it and the face of the head, and by moving the lever inan opposite direction the board is secured by the clamp firmly in place,and thus held While the cutters are cutting out the barrel-head.

By this arrangement I am able to cut out barrel-heads with greatfacility.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. The shaft 0, with its hollow conical head d, said head being providedwith adjustable cutting-bits f, in combination with the sliding head G,operated by the screw h and crank I, substantially as and for thepurpose above described.

2. The clamping-bar K, operated by lever L, in combination with thesliding head G and rotating cutter f, substantially as and for thepurpose described.

In witness whereof I hereunto set my hand and seal.
